Malkara (missile)
The Malkara (from an Aboriginal word for "shield") was one of the earliest guided anti-tank missiles (ATGMs). It was jointly developed by Australia and the United Kingdom between 1951 and 1954, and was in service from 1958 until gradually replaced by the Vickers Vigilant missile in the late 1960s. It was intended to be light enough to deploy with airborne forces, yet powerful enough to knock out any tank then in service. The basic form was later adapted for the short-range surface-to-air role as the Seacat and influenced the development of the Ikara. Development and operations Design was principally undertaken at the Australian Government Aeronautical Research Laboratory, and this phase was also one of the first examples of computer simulation in engineering design. Development testing was carried out at Woomera Prohibited Area, and approval testing at the tank training range at Lulworth Cove, Dorset. Although testing at Dorset apparently achieved an impressive 90% Pkill, in ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Aircraft Factories
Government Aircraft Factories (GAF) was the name of an aircraft manufacturer owned by the Government of Australia. The primary factory was located at Fishermans Bend, a suburb of Melbourne in Victoria. It had its origins in the lead-up to World War II, during which it was known as the Department of Aircraft Production (DAP). In 1987, GAF was reorganised and renamed as Aerospace Technologies of Australia (ASTA) then privatised. ASTA was purchased by Rockwell International, that was in turn purchased by Boeing a few years later. ASTA subsequently formed the nucleus of Boeing Australia. History World War II The entity was established just before the outbreak of World War II when the Australian government recognised that supplies of aircraft from traditional sources could no longer be assured. To ensure supply of aircraft, in 1939 the government set up the new Department of Supply and Development with an Aircraft Construction Branch within that department; both organisations offici ...

Hornet Malkara Img 2363
Hornets (insects in the genus ''Vespa'') are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets. Some species can reach up to in length. They are distinguished from other vespine wasps by the relatively large top margin of the head. Worldwide, 22 species of ''Vespa'' are recognized.A.H. Smith-Pardo, J.M. Carpenter, L.

Humber Hornet
The FV1620 Humber Hornet (FV1620, truck 1-ton, air portable, armoured launcher, Hornet launcher) was a specialised air-deployable armoured fighting vehicle designed to carry the Malkara, an anti-tank guided missile developed by Australia and the United Kingdom. History The Hornet was developed in the 1950s to provide British and Australian airborne units with an air-dropped long-range anti-tank capability. Based on the British Army's FV1611 Humber "Pig" one-ton four-wheel drive armoured truck, it carried two Malkara, missiles on a retractable boom at the rear, as well as two reloads. It could be transported by air in a Blackburn Beverley and air-dropped on a cluster of 6 special parachutes. Operation The gunner fired the missiles from inside the cab and controlled them by means of a joystick attached to a wire which unreeled from the rear of the missile and connected to the sights. Electronic signals controlling the missile's flight were transmitted through the wire. With a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joystick
A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It often has supplementary switches to control various aspects of the aircraft's flight. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. Aviation Joystic ...

MCLOS
Manual command to line of sight (MCLOS) is a method for guiding guided missiles. With an MCLOS missile, the operator must track the missile and the target simultaneously and guide the missile to the target. Typically the missile is steered with a joystick, and its path is observed through a periscope-type telescopic sight. The missiles are usually equipped with a magnesium flare in the base that automatically ignites on launch and allows the gunner to visually track the fast-moving missile in a manner similar in concept to tracer ammunition. MCLOS requires considerable training and practice to master, since even a minor disruption in the gunner's concentration would likely cause a miss. These guidance systems have marginal accuracy on tank-sized targets, even with perfect line-of-sight by the gunner, due to erratic flight paths requiring timely manual corrections. As demonstrated by the Israeli Army under fire from Soviet-armed Arab states, responding to the distinctive smoke puff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire-guided Missile
A wire-guided missile is a missile that is guided by signals sent to it via thin wires connected between the missile and its guidance mechanism, which is located somewhere near the launch site. As the missile flies, the wires are reeled out behind it (command guidance). This guidance system is most commonly used in anti-tank missiles, where its ability to be used in areas of limited line-of-sight make it useful, while the range limit imposed by the length of the wire is not a serious concern. The longest range wire-guided missiles in current use are limited to about . History Electrical wire guidance dates back to the early 20th century with an early example being the Lay Torpedo. A prototype ground-based electrical wire-guided torpedo was built by the Germans during World War II. The pair of deployed German guided air-delivered ordnance designs, the Fritz X and Henschel Hs 293, both used the ''Kehl-Straßburg'' radio guidance system for control. However, because the Briti ...

Pound (mass)
The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ″̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the abbreviation "lb"). The English word ''pound'' is cognate with, among others, German , Dutch , and Swedish . These units are historic and are no longer used (replaced by the metric system). Usage of the unqualified term ''pound'' reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms ''pound-mass'' and '' pound-force''. Etymology The word 'pound' and its cognates ultim ...

Solid Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants Rocket propellant is the reaction mass of a rocket. This reaction mass is ejected at the highest achievable velocity from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical ... (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Mamluk Sultanate, Arabs, Dynasties in Chinese history, Chinese, Ilkhanate, Persians, Mongol Empire, Mongols, and Delhi Sultanate, Indians as early as the 13th century. All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications for their simplicity and reliability. Since sol ...

Malkara
Malkara ( el, Μάλγαρα, Malgara) is a town and district of Tekirdağ Province in the Marmara region of Turkey. It is located at 55 km west of Tekirdağ and 190 km from Istanbul. It covers an area of 1,225 km², which makes the district the largest in Tekirdağ. Population of the town is 25,000 with another 36,000 residing in surrounding villages. The mayor is Ulaş Yurdakul ( CHP). Climate The district has cold winters, wet winds from the Balkans blow hard across Thrace. History Thrace was the scene of fighting during the Persian Wars and the name Malkara is said to come from the Persian 'Margaar' meaning 'cave of snakes'. Alternatively the town may be named after 'Malgar' a general in the army of Alexander the Great who built a fortress here after they had succeeded in bringing to an end the Persian 30-year occupation of Thrace. These fortifications remained in use up until the Byzantine period. Once the area had been brought under Ottoman control it was ...

British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centurion Tank
The Centurion was the primary British Army main battle tank of the post-World War II period. Introduced in 1945, it is widely considered to be one of the most successful post-war tank designs, remaining in production into the 1960s, and seeing combat into the 1980s. The chassis was adapted for several other roles, and these variants have remained in service. It was a very popular tank with good armour, manoeuvrability, and armament. Development of the Centurion began in 1943 with manufacture beginning in January 1945. Six prototypes arrived in Belgium less than a month after the war in Europe ended in May 1945. It entered combat with the British Army in the Korean War in 1950 in support of the UN forces. The Centurion later served on the Indian side in the Indo-Pakistani War of 1965, where it fought against US-supplied M47 and M48 Patton tanks, and it served with the Royal Australian Armoured Corps in the Vietnam War. Israel's army used Centurions in the 1967 Six-Day War, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HEAT
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
